What else can I help you with?
What chemical binds to the muscle cell memebrane causing a temporary rush of what into the muscle cell?
Acetylcholine binds to the muscle cell membrane, causing a temporary rush of calcium ions into the muscle cell. This influx of calcium triggers muscle contraction.
The combining of the neurotransmitter with the muscle membrane receptors causes the membrane to become permeable to sodium ions and blank of the membrane?
The combining of the neurotransmitter with the muscle membrane receptors causes the membrane to become permeable to sodium ions and depolarization of the membrane. This depolarization triggers an action potential that leads to muscle contraction.
When hinding of the neurotransmitters with muscle membrane receptors causes the membrane to become permeable to sodium resulting in the influx of sodium ions and what membrane?
action potential of the sarcolemma(the membrane)
Binding of the neurotransmitters with muscle membrane receptors causes the membrane to become permeable to sodium resulting in the influx of sodium ions an what of the membrane?
depolarization
The sites where a chemical substance is transmitted from the presynaptic terminal of an axon to the postsynaptic membrane of a muscle fiber are called?
The sites where a chemical substance is transmitted from the presynaptic terminal of an axon to the postsynaptic membrane of a muscle fiber are called neuromuscular junctions. At these junctions, the neurotransmitter acetylcholine is released from the presynaptic terminal and binds to receptors on the postsynaptic membrane, initiating muscle contraction.
What causes muscle or membrane inflammation?
Several conditions, such as multiple sclerosis, arthritis and lupus, cause muscle inflammation. Also overexertion in excerise can muscle inflammation
What are The sites where a chemical substance is transmitted from the presynaptic terminal of an axon to the postsynaptic membrane of a muscle fiber are called?
The sites where a chemical substance is transmitted from the presynaptic terminal of an axon to the postsynaptic membrane of a muscle fiber are called neuromuscular junctions. These specialized synapses facilitate the communication between motor neurons and muscle fibers, enabling muscle contraction. At the neuromuscular junction, neurotransmitters like acetylcholine are released, binding to receptors on the muscle membrane to initiate a response.
What chemical build up causes muscle fatigue and muscle cramps?
Lactic Acid.
What part of the muscle cell membrane contain acetylcholine receptors?
Acetylcholine receptors are located on the motor end plate of the muscle cell membrane. This specialized region is where the nerve cell communicates with the muscle cell, allowing for the initiation of muscle contraction in response to acetylcholine binding to its receptors.
What chemical on the muscle membrane destroys the messanger?
Acetylcholinesterase is the enzyme responsible for breaking down the neurotransmitter acetylcholine on the muscle membrane. This breakdown helps terminate the signal transmission at the neuromuscular junction.
Does Muscle movement driven by ATP is what type of energy?
Chemical energy creates ATP that allows muscle movement. Chemical energy is released in an chemical reaction that often causes heat.
What is the chemical used at the junction with a skeletal muscle?
The chemical used at the junction with a skeletal muscle is acetylcholine (ACh). It is released from the motor neuron at the neuromuscular junction and binds to receptors on the muscle fiber's membrane, triggering muscle contraction. This process is essential for voluntary movement and is part of the overall neuromuscular signaling mechanism.
